We like Ruby on Rails for its simplicity, its community and because it's a language that keeps developers happy. Convention over configuration makes development projects smoother, being able to focus on what really matters, and faster, not having to specify all the variables and configuration over and over again.
Furthermore, we love making apps that require little to no maintenance at all, and Ruby on Rails is perfect for that: by using style guides and writing clean code, it's easy to pick up where you left off some months ago.
Ruby has been in the market for over twenty years, and it's one of the most popular languages. Companies like NASA, Google, Spotify, Dropbox, LinkedIn, Twitter and the like use it.
Although we have such a defined toolset, we like playing with other technologies. At MarsBased, we value self-learning and we encourage our developers to come up with new ideas to test.
We're aware that not every size fits all, so if you've got other ideas, let us know. We most likely have given that language or framework a spin already, and there'll be someone in the team who can deliver properly.
As a result of this, we do have our own internal projects, which we've released as Open Source projects.
